There are fears that the almost 100 year-old Sykes-Picot Agreement - an Anglo-French plan that created modern day Lebanon and Syria - may be threatened by increasing sectarian fighting.

Jordan's King Abdullah II is urging the UN Security Council to declare the refugee crisis a threat to "the security and stability of our country." The Hashemite Kingdom is seeing between 1-2000 people crossing daily, putting strain on an already struggling economy and limited natural resources.

Lebanon, occupied by Syria from 1976 until 2005[3], is maintaining a fragile peace in spite of reported rocket attacks on the Bekaa Valley and occasional air raids by the the Syrian air force. The UN Refugee Agency says that Lebanon is currently home to 450,000 refugees causing friction in host communities with security forces imposing a nighttime curfew on Syrians.

Hezbollah[4] - the militant Shia organization - is also sending fighters to support embattled President Assad, with help from their Shia brothers in Iran, threatening to pull Lebanon back in to a state of armed conflict as sectarian divisions become more pronounced.

Iraq, too, is facing a wave of refugees and a new influx of returnees who left the country because of the US-led 2003 invasion. Kurds in Syria are becoming more powerful, which could spell trouble for Baghdad as its own Kurdish community begins to feel more emboldened after years of struggle following the collapse of the Ottoman empire.

The Syrian struggle is felt across north Africa too, as refugees flood into Egypt, with men in Cairo looking for ‘cheap’ Syrian brides. In Tunisia, teenagers are among those taking up arms following the the call to Salafis to join the fight.

The conflict has altered the region, and there is every chance that the Syrian civil war will have be a turning point in Arab history.
